Production of plants through anther culture and their seed bearing ability in Chinese cabbage

Anther culture of heading Chinese cabbage, Brassica campestris ssp. pekinensis, was carried out with several cultivars for 3 years. Plants derived from microspores were investigated for pollen production, self-and cross-incompatibility and seed bearing ability. Genotypic specificity of the donor plant was obvious in microspore embryogenesis. Sixty five out of 103 anther-derived plants produced pollen and self-seeds. The low ability of self-seed setting in bud pollination at the first generation of anther-derived plants was greatly improved according to advancement of generation. The number of seeds per open flower pollination in cross-compatible combinations was greatly more than that per bud self. All of the lines derived from the anther of F₁ hybrids were so uniform in morphology that they could be used directly as the parental inbred of an F₁ hybrid.
